Browns quarterback Brandon Weeden is being treated for a concussion and it's not yet known if he'll play this week at Oakland.

Weeden was injured in the closing minutes of Sunday's 20-14 win over Pittsburgh. He was replaced by backup Colt McCoy, who would play against the Raiders if Weeden is not cleared.

Browns coach Pat Shurmur said Weeden was at the team's facility Monday and is going through the "strict concussion protocol." Shurmur would not say if Weeden did any physical activity. Shurmur would not predict if Weeden will be able to play and said he'll know more about his status Wednesday.

Weeden banged his head on teammate Joe Thomas' leg as he fell awkwardly in the fourth quarter. McCoy came in for Cleveland's final two series.
